In this program, we demonstrate how to follow a line with a SPIKE robot and then align to that line. That way the robot can position itself at specific distances on a predetermined path.

This program was intended for and tested on the Gazon robot

In this program, we present an "MY BLOCK" that follows a line presented as a yaw angle from the robot's starting position. If the program acts differently when tested again, then the most likely problem is the direction the robot is facing, when starting the program. Make sure to place the robot at the correct starting position with the correct facing direction, before every test.

In this program we demonstrate how to program a SPIKE robot to follow a line with the aid of a color sensor. Make sure the line is big enough for the sensor to detect it and react to it. For some thinner lines, the speed of the robot can be lowered, but if that does not help, the program can be easily adapted to work with reflected light intensity.

In this program we demonstrate how to program a SPIKE robot to follow a line with the aid of a color sensor. Make sure the line is big enough for the sensor to detect it and react to it. since we are measuring reflected light rather than the color of the line, we can and have implemented multiple states line following.

In this program we demonstrate how to program a SPIKE robot to follow a line with the aid of a color sensor. In this program, we use the sensor value to calculate a number to feed in the "start moving" command. The numbers in this program depend highly on the size of the wheels of the robot, the distance between the wheels, the color sensor reflected light range, the wheels friction, and the speed at which the robot moves. The numbers in the program must be adjusted for every case, and are in no meaning optimal to use as is, in other projects.

In this program we demonstrate how to program a SPIKE robot to align to а line with the aid of two color sensors. Make sure the line is big enough for the sensor to detect it. For this program to work, the sensors must be placed in front of the wheels.

In this program we demonstrate how to program a SPIKE robot to align to а line with the aid of two color sensors while moving backward. Make sure the line is big enough for the sensor to detect it. For this program to work, the sensors must be placed in front of the wheels.

In this program we demonstrate how to program a SPIKE robot to follow a line with the aid of one color sensor and detect an intersection with another color sensor. Make sure the line is big enough for the sensor to detect it and react to it. For some thinner lines, the speed of the robot can be lowered, but if that does not help, the program can be easily adapted to work with reflected light intensity.

This program was intended for and tested on the Gazon robot

In this program, we demonstrate how to program a SPIKE robot to follow a line with the aid of one color sensor and detect and stop at the second intersection with the aid of another color sensor. Make sure the line is big enough for the sensor to detect it and react to it. For some thinner lines, the speed of the robot can be lowered, but if that does not help, the program can be easily adapted to work with reflected light intensity.

This package contains the three blocks used in the advanced calibration section of the FLL course.

The blocks contained are:

• InitiArray block
• CalibrateMinMax
• GetCalibrateValue 

This is the example program using the blocks available at  Blocks Package for Advance Calibration of LEGO Mindstorms EV3 Color/Light sensors. The program makes the robot find the minimum and maximum values and to calibrate the current sensor value depending to the min and max.
